Salsa Spearfish Riders - your views please!

If any of you have ridden El-Mariachi and Spearfish, I'd love to hear your views on how they compare. I've never ridden a Spearfish. I love my El-Mar Ti - it's fabulous overall but just sometimes I could use a little rear suspension of calm down the rear end on fast, bumpy descents. Overall the El-Mar is that good that I can accept this, but am still curious about the spearfish.
